'93-'95 3rd gen RX-7
LT1/LS1 Conversion Packages
We make parts for installing both the LT1 and LS1 engines into the 3rd gen RX-7. While the LT1 engine fits with little room to spare, the LS1's throttle body is almost 3/4" taller in the critical distance between the FD's stock steering rack and hood skin. Because of this, a critical decision must be made with regard to LS1's engine location. The Mazda engineers blessed the FD with nearly perfect race car steering geometry, so we prefer to keep the steering rack in it's stock location. But there has to be a compromise somewhere, so we offer 2 versions of our FD/LS1 swap packages...
...LS1- STD Version...features stock steering rack location but requires hood modification. To see the FD/LS1 hood modification page, CLICK HERE.
...LS1- Underhood Version...(Basic Series Only) features lowered steering rack and engine location. "bump-steer" correction should be used, but not required. LS1 throttle body clears the stock RX-7 hood, so NO hood modifications are needed.
Be sure to mention your choice of engine location when you order.
